Why it works: Peas and walnut work together. They rank in the top 14% of all ingredient pairs, and cooks put them together in 170 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
Peas
Ingredients
Directions
Cook the peas
Fill a saucepan with water, add a pinch of coarse sea salt, and bring to a boil.
Add the shelled peas and boil until almost tender, about 15-20 minutes; do not cover the saucepan.
Drain the peas and place them in a shallow pan.
Finish and serve
Add the butter, sprinkle with white sugar and a pinch of salt, and shake over low heat to coat the peas with butter.
Transfer to a serving dish and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Freshly shelled peas
- Provide the main body and sweet, vegetable flavor of the dish.
- Butter
- Adds richness and a glossy coating that carries flavor across the peas.
- White sugar
- Adds sweetness that balances the peas' natural vegetal taste.
The step that matters
Boiling the peas uncovered until almost tender. Peas cooked in a covered pan can turn dull and olive-green because trapped acids build up. Boiling uncovered lets volatile compounds escape, helping them stay bright green. Stopping at almost tender keeps them from turning mushy during the final shaking with butter.
Swap the peas
How well each one fits the dish's main ingredients (butter, walnut, sugar):
- Almondfits better
- Macadamia nutfits better
- Pistachiofits better
- Peasthe original
Fit is the average pairing score against butter, walnut, sugar. Candidates are from the same food group and used in at least 100 recipes.
